摘　　要：辽河油田低渗透油藏的地质储量占各类油藏地质储量的7.7%,开采程度较低。处于中晚期开发阶段的辽河油田,挖掘渗透油藏的地质储量,其采收率如果能够提高1%,那么将会获得非常可观的经济效益。压裂是改造低渗透油层提高油井产量的强化措施。本文以欢北地区低渗透油层——杜家台油层为例,对低渗透油层压裂施工工艺进行了研究和探讨,提出了适合低渗透油层的及压裂液、支撑剂和施工工艺。The Geological reserves of LiaoHe oilfield low permeability reservoirs accounts for each kind of oil reserves 7.7%.The mining degree is low. In the advanced stage of development of the Liaohe Oilfield,Mining permeability reservoir of geological reserves,its recovery ratio can enhance 1%,then it will be very considerable economic benefits. Fracturing is the transformation of low permeability oil wells increased production of strengthening measures. In this paper,Huan North low permeability reservoirs,for exa...
